In some areas of endemic trachoma, muscoid flies may play a significant role in transmission of this serious eye infection. A simple and practical method of quantifying the relative household density of synanthropic flies has been developed for use in epidemiological field surveys. The method uses two boards moistened with a 10% sucrose solution. The fly scores showed good reproducibility at the same sampling site during the day and on different days. The only flies identified were Musca sorbens, showing their local density and a significant association of this fly with the presence of inflammatory trachoma in children.
在一些地方性沙眼流行地区，家蝇可能在这种严重眼部感染的传播中发挥重要作用。已开发出一种简单实用的方法来量化喜人居的家蝇在家庭中的相对密度，用于流行病学现场调查。该方法使用两块用10%蔗糖溶液浸湿的板子。在白天的同一采样点以及不同日期，家蝇得分显示出良好的可重复性。唯一鉴定出的家蝇是厩螫蝇，显示出它们在当地的密度以及这种家蝇与儿童炎性沙眼的存在之间存在显著关联。
